Stream live upgrade progress (Server-Sent Events)

GET 
/api/admin/settings/upgrade/stream

Server-Sent Events stream of an in-flight upgrade: the coarse phase from status.json plus new lines from the updater's progress.log, pushed as they appear so the Updates UI shows real-time progress without polling or a manual refresh. Closes when the upgrade reaches a terminal phase (or after a time cap). System administrators only.
